Hannah Kobayashi’s disappearance remains a mystery as her family and friends desperately search for answers piecing together what happened to her and what may have led to her radio silence.

According to the Los Angeles County Medical Examiner, Ryan Kobayashi’s cause of death was “multiple blunt force traumatic injuries.”

Hannah Kobayashi, 30, was travelling from Hawaii to New York City for a new job earlier this month but she vanished during a layover in Los Angeles, her family says. As they searched for Kobayashi, the family suffered another tragedy.

Ryan Kobayashi, the father of missing Hawaii woman Hannah Kobayashi, was found dead in a parking lot near LAX on Nov. 24, according to police.
